THREAD-WINDER.

SPECIFICATION forming part of Letters Patent No. 642,281, dated January 30, 1900.

Application filed June 13, 1898. Serial No. 683,249. (No model.)

To all whom it may concern:

Be it known that I, DICKERSON G. BAKER, a citizen of the United States, and a resident of "Willimantic, in the county of WVindham and State of Connecticut, have invented certain new and useful Improvements in Thread- Winders, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

Myinvention relates to the class of devices used for building up a mass of thread on a core; and the object of my invention is to provide a device of this class which may be run at a comparatively high rate of speed, thus increasing the capacity of the device, and one in which the character of the work produced shall be of a comparatively high grade.

To this end my invention consists in the device as a whole, in the combination of parts, and in the details and their combination, as hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a top or plan view of a machine embodying my invention with parts broken away. Fig. 2 is a view in side elevation of the same with parts out in central section. Fig. 3 is a detail end view in section through the traversedrum on the line a: as of Fig. 2. Fig. 4 is a diagram view illustrating the relative position of the parts at a preliminary step in the winding operation. Fig. 5 is a like view illustrating the relative position of the parts at a more advanced stage in the operation of winding.

In the operation of winding thread, as on a bobbin or the like, prior to my invention a difliculty has been experienced in attempts to run the spindle at a high rate of speed, in the tendency of the thread to jump, and a consequent loosening thereof between the guide and the bobbin, the proper tension on the thread to produce desired results in the finished bobbin being insuflicient to prevent such jumping and consequent loosening. An objectionable resultof this action is a bobbin less compactly wound than where the tension of the thread is preserved at all times, the lay being uneven and a bobbin being produced having an uneven surface at the end thereof.

In the Within-described device means are provided whereby an even tension is pre* served at all points along the length of thread to the point of its delivery onto the bobbin, and the machine may be run at an extremely high rate of speed without any lessening of the tension or any jumping of the thread.

In the accompanying drawings there is illustrated a form of device for practicing the invention, in which the letter a denotes legs or supports, upon which is mounted a table b. Adriving-shaft o, carryinga driving-pulley c, is borne in the supports a, a belt 0 extending from the pulley c to a traverse-pulley d, located on the traverse-shaft d. This traverse shaft is mounted in standards I) on the table I) and also is supported at one end by a traverse-drum standard g. A gear (1 is secured to one end of the traverse-shaft and is in mesh with a winding-gear c on he windingspindle e. The opposite end of the traverseshaft bears traverse-drum pinions d in mesh with gear-teeth f, formed on the outer surface of the traverse-drum f.

A sleeve g is mounted in the traversedrum standard g and has a rotary movement therein, this sleeve projecting on opposite sides of said traverse-drum standard. Traverse-drum cases 9 are secured at each end of the sleeve g in any suitable manner, in the form shown the cases being split on one side, and clamping-bolts g", as shown in dotted outline in Figs. 3 and 4 of the drawings, are employed to clamp the cases tightly upon the sleeve g. These cases surrounding the traverse-drum have recesses 9 receiving that,

portion of the drum bearing the gear-teethf. Collars f are clamped to the drum close to each of the cases for preventing endwise movement of the drum therein. The traverse-drum pinions d are located in pinionrecesses g in the lower side of each of the cases, and plates 9 g located outside of the 5 gear-teeth f and traverse-drum pinions (1 close the recesses g and g respectively.

The winding-spindle e is arranged to hold a core h, usually formed of paper, upon which the thread is to be wound. A guide-slot i is formed through the wall of the traverse-drum f, this slot extending in a helical path for a portion of the way only about the drum and then in another helical path in the opposite direction about the drum to a point on a circumferential line coincident with the starting-point. The drum is caused to revolve with especial reference to the revolutions of the winding-spindle, and the guide-slot in the drum may be formed to cause the thread to travel'from end to end of its path on the winding-spindle any desired number of times in a single revolution of said drum, the variation of this guide-slot or the changing of the relative rotation of the drum and spindle producing a variety of winds on the bobbin built up on the core supported on the spindle.

A bridge Z extends through the drum from end to end, this bridge being supported at position to cause the tension n borne on the tension-arm n, to move the drum to one side out of its normal position, a spring a or like device being employed to hold the tension continually in engagement with the surface against which it bears.- In the formshown the tension n bearsagainst the-casing within whioh tli'e drum is located and on that'side of a line drawn through the axes of the wind ing-spindle and the driving-shaft of the traverse-drum opposite to that from which the thread is being led through the guide-slot in the drum. This pressure of the tension causes I the drum to be tilted toone side on the-pivot formed by the sleeve g, causing the bridge or inner surface of the drum to lie continually in contact with the mass of thread beingbuilt upon the core on the winding-spindle.
